摘要：

This paper presents a case-study that highlights the importance of sustainable machining technologies in achieving sustainable development objectives. A technology evaluation was undertaken to understand the likely impacts of the use of technology on sustainability performance measures. The evaluation is more than an experimental method for supporting the design of technology and an instrument for supporting decision-making. It is also a tool for supporting technology policy and for encouraging its adoption and application in industry. More specifically, a sustainability evaluation of cryogenic and high pressure jet-assisted machining in comparison to conventional machining is examined. Sustainability performance measures refer to environmental impact, energy consumption, safety, personal health, waste management, and cost. The case-study refers to the machining of high-temperature Ni-alloy (Inconel 718). It is shown that tooling costs represent the major contribution to the overall production cost, which contradicts previous analyses, and that sustainable machining alternatives offer a cost-effective route to improving economic, environmental, and social performance in comparison to conventional machining.
